Cr2O3 تأثير التشعيع بأشعة γ على الثوابت البصرية للغشاء الرقيق المحضر بطريقة الترسيب الكيميائي الحراري


Thin film of Cr2O3 are prepared by chemical spray pyrolysis at (450°C) of the thickness (245) nm. X-rays diffraction is used to identify its structure. Optical constants likes absorption coefficient; extinction coefficient exposure to the gamma radiation., refractive index, as well as the real and imaginary parts of dielectric constant are studied. Then, the effect of γ- radiation Cs137 on optical constant of the prepared films clear as it compared with that is not.
